EQ overflowing. Additional events will be discarded until existing events are processed.

Got this error while watching youtube. Screen wen completely blank and I had to Ctrl+Alt+F2 to save the xorg log. This was on 310.19 with 3x GTX480 in SLI with Ubuntu 12.04. Happens on a daily basis with SLI enabled it seems. Also the Flash Color VDPAU bug with youtube is back with this driver. This is the whole error message:

hello , i am using the same driver 310.19 ( NVIDIA-Linux-x86-310.19.run
) without sli . i can use youtube with HW acceleartion enabled without Problem . If you are using a ppa edegrs drivers the Problem may occure . I got a lot of segemtation fault with ppa edgers drivers , it is because a precompiled does not much with kernel version in use.i suspect it is kms conflicting Bug…
may be , may be not

read this (https://devtalk.nvidia.com/default/topic/522835/linux/if-you-have-a-problem-please-read-this-first/) and attach the log, rename it as JPG
